Perhaps it's not surprising that balmy Hawaii is home to a company that's pushing the envelope of solar thermal technology. Start-up Sopogy, based in Honolulu, has taken the basic design of large solar thermal power plants and shrunk it down so it can fit on a building's roof.
Demo models of its electricity-generating solar collectors--essentially metal half-pipes with a reflective coating--are now being tested with a Fortune 500 company and a few utility customers, according to company president and CEO Darren Kimura.
To expand, this fall the venture-funded company intends to raise an additional $9 million, which it hopes to secure by the end of the year, he said.
Concentrating solar power, or CSP, uses reflective troughs or dishes to concentrate sunlight to heat a liquid that flows through a pipe above the troughs. That heated liquid, which can be oil or water, is converted into steam to turn an electric turbine.

These panels protect all optics, reflectors and vital system components from the elements and storms. rare land availability.

Darren Kimura learned early to use his imagination.
Growing up on the Big Island, the emerging renewable energy entrepreneur didn’t have much entertainment to distract him.
“A lot of successful business people come from the Big Island,” he said. “The key about Big Island is we go out and make something happen, we don't just wait to buy it.”
Kimura, 32, is president, CEO and chairman of Sopogy Inc., which the state in June approved for $10 million in special purpose revenue bonds for a new solar farm power plant in West Hawaii.
